Title: Shoe press
IPC: A43D25/07
Filed: 1943-06-24
Abstract: 572,838. Sole-laying presses. COMPO SHOE MACHINERY CORPORATION. June 24, 1943, No. 10236. Convention date, June 2, 1942. [Class 17 (i)] A shoe press, particularly for use in cementing soles to lasted shoe uppers, comprises two opposed flexible diaphragms both of which are pressed outwards during the operation of the press, the shoe clamping means being operated by admitting fluid to a chamber bounded on one side by one of the diaphragms to press the shoe against the other. In the form shown, a lower or shoeclamp operating diaphragm 15 and an upper or sole-pressing diaphragm 17 are clamped at their edges between a frame casting 10, with hollow core 11, and an ovalshaped ring 13. A rigid pressureresisting plate 16, preferably contoured at the central part to the general shape of a shoe bottom, is clamped between them. The diaphragm 15 in the non-inflated condition assumes the same general shape as the central part of the plate 16. Toe and heel clamping means 20, 40 are pivoted at 36, 45 respectively in bosses 32, 46 on two pressure platens 33, 37, pivoted in frame 10 under the action of torsion springs 36, 50, to press against the lower diaphragm 15. In use, starting with both chambers 18, 19 deflated, pressure fluid is admitted to chamber 18 at valve 62 at first to dilate diaphragm 15 and cause the clamping means 20, 40 to become operative. Increase in pressure, due to admission of further fluid, lifts a leaf-spring valve 65 to uncover a port 64 in plate 16, to dilate the diaphragm 17 and allow any desired pressure to be applied to the sole. The combined areas of the platens 33, 47. are greater than the area of the sole of largest shoe to be dealt with. A leaf spring covering the underside of a second port in the plate 16 allows the chamber 19 to be deflated through the chamber 18 and valve 62. The chamber 19 may, if desired, be filled with a liquid, thus dispensing with the ports 64. Alternatively, each chamber 18, 19 may have its own inflating and deflating valves. The press is adapted to be used in a machine of the kind described in Specification 379,884.

Title: Improvements in or relating to machines for helically winding wire on a travelling mandrel wire
IPC: C01B25/30
Filed: 1925-04-20
Abstract: 233,330. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. April 29, 1924, [Convention date]. Coiling; formers; winding. -In a machine particularly adapted for manufacturing helical wires for electric incandescent lamps wherein the winding wire is wound by a rotating winding head on a mandrel wire travelling normally at a uniform velocity and intermittently at a much greater velocity to produce wire helices separated by portions of greater pitch or almost straight, the means for producing the increased velocity comprises an independent source of energy, such as a pneumatic cylinder, which is controlled by the driving mechanism. The mandrel wire 30 passes from a supply spool 32, over a feed roll 34<1> on a shaft 29, through a winding head 11 carrying a spool 38 of winding wire, over a second feed roll 43 on a shaft 27, and is finally rewound on a roller 47. Winding head 11 is driven uniformly from the main shaft 2 by worm gears 8. 10. The main shaft 2 drives by means of change-speed gearing 14, 15, 20, 21, Fig. 2, a transverse shaft 18 carrying a worm 22 engaging a worm wheel 23, which drives a shaft 24 through a roller coupling 100. One end of the shaft 24 is geared by pinions 84, 85, and worm-gearing to the shaft 27 of the mandrel wire feed roll 43, and the other end of the shaft 24 is geared to the shaft 29 of the other feed roll 34'. The roller clutch is of double construction shown in Fig. 4: the inner rings 92, 99 are pinned together and to the shaft 24, one outer ring 91 is rigid with a bushing 90 turning with the worm wheel 23, and the other outer ring 100 is loose on the shaft and carries a pinion 83. During the periods of normal winding the rotation of the worm wheel 23 rotates the outer ring 91, which carries round with it the shaft 24, thus driving the mandrel wire feed roll shafts 27, 29 uniformly. The separate source of energy for speeding up the mandrel wire comprises a vacuum cylinder 75 in which a vacuum is maintained below the piston 76 by means of a suction port 72 to keep the piston depressed. Another port 71 admits air below the piston when a valve 69 is raised by a rod 67 connected to a lever 65 actuated by a cam 64 on a shaft 63 geared to the main shaft 2, so that after a predetermined number of turns have been wound on the mandrel wire the piston 76 is raised by the action of a spring 88, and a gear segment 80 on a lever 78 connected to the piston rod 77 is actuated. The gear segment 80 drives by means of gearing 81, 82 the pinion 83 rigid with the outer ring 100 of the roller clutch, moving it round rapidly, and so speeding up the shaft 24 and the mandrel wire feed roll shafts geared thereto. The normal slow rotation of the shaft 24 by the worm wheel 23, outer ring 91 and inner rings 92, 99 is resumed as soon as the piston reaches the limit of its upward movement, the outer ring 100 rotating freely on the inner ring 99 during its reverse rotation as the piston descends.

Abstract: 1298693 Extruding scrap plastics GLOUCESTER ENG CO Inc 4 March 1970 [13 March 1969] 10361/70 Heading B5A In the screw extrusion of ground plastics scrap material fed to an extruder barrel from a hopper 26, adhesion of molten material to the screw 66, and rotation therewith without axial displacement in a screw and barrel feeding region 56a, is prevented by water cooling of the screw and axially extending grooves 57 in the barrel interior. In the described embodiment, wherein the barrel extends vertically with a crosshead outlet 40 at the lower end thereof and the hopper 26 at the upper end thereof, the grooves 57 are defined by planar surfaces intersecting at 90 degrees, and the cooling water circulates via concentric passages 98, 94 which are connected to concentric pipes 73, 72 extending through the hopper 26, the pipe 72 carrying an upper agitator (86), Figure 1 (not printed), and the screw flights also extending into the hopper 26 whereby bridging of the material within the hopper 26 is avoided. The barrel is heated by bands (59) along the length thereof and the screw shank 112 extends outwardly from the lower end of the barrel through a seal 152 to a driving gear box 119, the outward extension of the screw being provided with concentric passages 127, 138 for the circulation of cooling fluid and being heat insulated from the screw within the barrel by an air containing chamber 117. The sealing member 152 is provided with a threaded internal configuration which acts to restrain leakage of plastics from the barrel around the downward screw shank extension, a clearance being provided between the threads and the shank to accommodate eccentricity of the screw, and the clearance decreasing outwardly from the barrel e.g. from À005 to À001 inch. The screw employed is of 4 inch diameter, with a length of 12 or 14 diameters, and the grooves 57 are preferably greater in number than 10. In the described embodiment, plastics film e.g. À0005 to À010 inch thickness, is cut in a grinder into flakes of ¢ to 3/4 inch diameter, and delivered therefrom to the hopper 26, via a blower and a cyclone. The extrudate from the die, connected to barrel crosshead passage 40, may define a sheet or film, or alternatively a plurality of strands are ground by a pelletizer which draws them through a water cooling trough and a drier.

H.], and POOLE, D. C. E. April 26, 1945, No. 10487. [Classes 54 and 135] A prepayment gas meter has a byepass to the auto-valve for maintaining the small supply necessary for such apparatus as a refrigerator when the auto-valve closes when the prepaid amount has been consumed, and one or more pressure-operated safety-valves are arranged in the delivery to other and large consumption apparatus and operate to cut them off, should they be left on or inadvertently turned on, when the auto-valve is closed. Accidental interruption of the small supply to the refrigerator &c. is thus avoided. The cost of the byepassed gas is recovered from the subsequent prepayment, e.g. as described in Specification 509,625. A suitable safety-valve comprises a valve element 24 for closing a port 29 between an inlet 26 and an outlet 30 which is connected to the large consumption apparatus. The refrigerator or equivalent may be connected to the branch 27, shown blanked off, or otherwise on the mains' side of the valve. The valve element 24 is carried by a diaphragm 23 which lifts it off the port 29 under a full pressure, but allows it to drop back when the pressure falls as the auto-valve closes. An adjustable byepass 41 enables pressure to build up on the diaphragm for opening the valve when the full supply is restored by prepayment, and provided no large consumption apparatus is then turned on. A plunger 31 resting on the diaphragm passes through the cover 32 and indicates whether the valve is open or closed.

Title: Improvements relating to the catalytic hydrogenation of carbonaceous materials
IPC: C10G1/08
Filed: 1931-04-10
Abstract: Carbonaceous materials such as tars, oils, naphthalene, are hydrogenated at elevated temperature and pressure in the presence of iron, cobalt, or nickel or their compounds, together with sufficient hydrogen sulphide to produce a greater yield than would be obtained using only the sulphides of these metals as catalysts. The catalyst is preferably the metal or its oxide, and is converted into the sulphide in the early stages of reaction.  The hydrogen sulphide may be added as such, or may be formed from sulphur, thiophene, carbon disulphide, or other sulphur compounds; the excess of hydrogen sulphide beyond that required to combine with the catalyst should be from 1 to 15 per cent of the initial material; the optimum amount for each material is found by preliminary experiment.  In hydrogenating naphthalene, the reaction may be carried out below about 480 DEG  C., producing tetra- and decahydronaphthalenes, or above about 500 DEG C., in which case the ring is split into benzene hydrocarbons.
